ddecker                 Template for a double decker plot. A double
                        decker plot is composed of a sequence of spines
                        in the same direction, with the final spine in
                        the opposite direction.
geom_mosaic             Mosaic plots.
hspine                  Horizontal spine partition: height constant,
                        width varies.
mosaic                  Template for a mosaic plot. A mosaic plot is
                        composed of spines in alternating directions.
